1. Maybe is not good enough.
2. OK then, people will beg for officer/recruiter/GM only for a day to get a badge, and then they can do a nuke. That's not good
3. That's not a solution. What if the GM kid is rude? Members should act like slaves?
4. It can happen. The majority of players have a negative PvP KDR. If you check guild ranks in forums you can see that PvP KDR counts for guild ranking in multiple categories, PvE KDR only 1.
5. Still bad. The requirements to be a member to get a badge is set by the "rude kid GM". That's not good.
